De La Puente, 24, was waived Monday by Kansas City. The 6-3, 308-pounder played center at California, but is being called a guard by the Seahawks.

De La Puente was undrafted in 2008, then spent camp with the San Francisco 49ers before being waived. He then signed with the Chiefs and was on their inactive list for seven games before being placed on the practice squad for the rest of the season.

Ruegamer, 33, was an 10-year NFL vet who signed with the Seahawks just prior to the start of training camp. But he suffered an elbow injury in the early going and missed much of camp until returning to the practice field Tuesday.

However, he didn’t take part in any of Tuesday’s drills and was released shortly after.

The Seahawks are badly in need of bodies on the offensive line with center Chris Spencer and tackle Walt Jones not expected to be ready for the start of the regular season and guard Mike Wahle waived injured before camp started.
